I hope this I can put this here...

[RoKeT]

These are just my studies on it, for now I just want a copy somewhere safe to put it, and I know this would work... please, you don't have to critisize me for answers or not they aren't reviewed yet, I'm just real busy in RL to, so I"m not done my studies and woudl love to be able to update this as I go along... also, if anyone is into physics, I would like to get into Astro personally a bit more, and I could always use help aswell but for now at the very least this is the basics of physics so someone might want to read it and learn a little bit... if it's the wrong place feel free to move it... I just wanted a secnodary place to put my research up incase soiemthing happens to my comp

PART ONE!

At its root, physics is all about making measurements (and using those measurements
as the basis of predictions)

physics uses a number of measurement systems, such as the
CGS (centiment-gram-second) system and the
MKS (meter-kilogram-second) system.
You also use the standard English system of inches and feet and so on that’s the FPI (footpound-
inch) system


all measurements (except for some angles) have units, such as meters or seconds.
For example, when you measure how far a hockey puck slid, you need to measure both
the distance in centimeters and the time in seconds.





CGS Units of Measurement- (centiment-gram-second)

Measurement Unit Abbreviation
Length centimeter cm
Mass gram g
Time second s
Force dyne dyne
Energy erg erg
Pressure barye ba
Electric current biot Bi
Magnetism gauss G
Electric charge franklin Fr



MKS Units of Measurement- (meter-kilogram-second)
Measurement Unit Abbreviation
Length meter m
Mass kilogram kg
Time second s
Force Newton N
Energy Joule J
Pressure Pascal P
Electric Current Ampere A
Magnetism Tesla T
Electric Charge Coulomb C


PART TWO!

Scientific notation is expressed as a number multiplied by a power of 10.


You convert a number to
scientific notation by counting the number of places you have to move the decimal
point to get the first digit in front of that decimal point. For example, 0.050 is 5.0 × 10–2
because you move the decimal point two places to the right to get 5.0. Similarly, 500 is
5.0 × 102 because you move the decimal point two places to the left to get 5.0.

Example.
0.0000000000000000000000000000091 kg Convert to
9.1 × 10–31st power* kg- Easier to work with!


PART THREE!

Physics problems frequently ask you to convert between different units of measurement


CONVERSION CHART FOR BASIC PHYSICS!
 1 m = 100 cm = 1000 mm (millimeters)
 1 km (kilometer) = 1000 m
 1 kg (kilogram) = 1000 g (grams)
 1 N (Newton) = 105 dynes
 1 J (Joule) = 107 ergs
 1 P (Pascal) = 10 ba
 1 A (Amp) = .1 Bi
 1 T (Tesla) = 104 G (Gauss)
 1 C (Coulomb) = 2.9979 × 109 Fr

Remember on thesis and Theries the higher the number the worst it is, like say this
p=.001 very good p=.05 good
